JavaScript中避免Form重复提交的两种方案

1、javascript ，设置一个变量，只允许提交一次。

<script language="javascript">

var checkSubmitFlg = false;

function checkSubmit()

{

if (checkSubmitFlg == true)

{

return false;

}

checkSubmitFlg = true;

return true;

}

document.ondblclick =

function docondblclick()

{

window.event.returnValue = false;

}

document.onclick =

function doconclick()

{

if (checkSubmitFlg)

{

window.event.returnValue = false;

}

}

</script>

<html:form action="myAction.do"

method="post" onsubmit="return checkSubmit();">

2、javascript，将提交按钮或者image置为disable

<html:form action="myAction.do"

method="post"

onsubmit="getElById('submitInput')

.disabled = true;

return true;

">

<html:image

styleId="submitInput"

src="images/ok_b.gif"

border="0" />

</html:form>
